they are really expensive because they want to make lots of money. when they say they are the only vitamins that are truly absorbed by the body they are lying. amway is a money make scheme/scam and their vitamins are no bettr or worse than anything you will get from someplace like http://www.swansonvitamins.com which is the cheapest vitamins on the net (don't know how much to ship to india is though)
don't listen to their pr bs, go find something affordable and enjoy.
